That looks a bit crazy. Why would windshear suddenly pitch the nose down so abruptly? Fair enough the @rse drops out of it if you lose speed, but that was a violent pitch down. That was not the secondary effect of controls lowering the nose because the speed has reduced. Something fishy somewhere. Reminds me a bit of that Prune 787 (IIRC) video of weird nose down pitches on short final. Brother of MACS??
